Overview
Most studios do not fail because the idea was bad; they fail because they spend too long on the wrong version of it. Prototyping fixes that.
Prototyping Workflow
A solid prototyping workflow runs through the same loop. Skipping a step will cost you downstream.
- Define core mechanics
- Rapid prototyping
- Feedback and iteration
- Concept validation
Common Pitfalls
| # | Pitfall | Description |
|---|---|---|
| 1 | Overambitious scope | Lock the core loop before layering anything else on top. Complexity hides broken mechanics. |
| 2 | Skipping feedback | Short cycles with real users consistently beat long internal reviews. |
| 3 | Polishing too early | If it looks great before it plays great, you have made a mistake that is more expensive to delete. |
| 4 | Poor onboarding | If players cannot figure it out in the first session, the problem is the introduction, not the mechanic. |
Choosing the Right Question
Pick the one that answers the question your current prototype is asking. One question per prototype.
Key Metrics to Track
- Win Rate
- Level Churn
- Day‑1 Retention (D1 Retention)
- Cost Per Install (CPI)
- Playtime
Prototyping Principles
- Ugly is fine – focus on functionality before aesthetics.
- Speed beats polish – iterate quickly.
- Real users, not teammates – gather feedback from actual players.
- One question per prototype – keep each test focused.
- Kill bad ideas early – discard concepts that don’t work.
- Do not fall in love with version one – stay open to change.
- Prototype the riskiest part first – address the biggest uncertainties early.
Conclusion
Prototyping is not a step to skip; it is the step that saves everything that comes after it. Fail fast, learn faster.
